I have a couple of issues maybe someone can help me worh. First does the leopard wait till there is no x10 signals on the line before sending it's singal. I have three x10 motion sensors that when they are active time events from the leopard dont come on. Now I have rr501 which waits but if the leopard doesn't wait I could have a signal collision. The next things is if I move the tw523 to another outlet x10 the leopard doesn't send signals but it does receive them. The x10 light on the screen blinks but the tw523 doesn't blink. Now I would think it would be the cable but if I put it back to the outlet I originally had it in it works fine. I'm trying to move because I have a couple of transformers in the same outlet that I can't move and I'm trying to see if that's the x10 problem I having. The next thing is funny the tw523 is not polarized so it can go in the outlet anyway my tw523 only works when it's upside down does anyone know why this is? Thanks Dave

Yes the Leopard will "wait" in the sense that it will not transmit anything if a X10 signal is being received. But it cannot know for sure that there is no X10 activity on the power line because the TW523 will only transmit the second copy of a received X10 signal to the Leopard, so there is a small chance that there might still be a collision.

X10 motion sensors are notorious for creating lots of X10 traffic, so you might be seeing more delays in the Leopard sending signals due to those.

If the TW523 won't transmit a signal when its in a certain outlet, it is usually because you have some kind of "signal sucker" on that circuit that is preventing it from receiving its own transmission. I made a modification on my own TW-523s that helps somewhat with this, as seen here:

Then there is Jeff Volp's notes and products in helping with X10 signal problems:

If you have a second TW-523 handy, try plugging it in next to the outlet you're using with your first TW-523 (with nothing plugged into it's RJ11 jack). I've seen that help in transmitting a signal because of of the tank circuit effect it adds to the power line.

Guy adding a second TW-523 to the outlet worked great thanks for the help.
